Application inea Juiy' ao, iaaa ser'iai No. 654,714.

The present invention appertains generally to improvements in direction indicators l foi) motor vehicles and specifically/to a side novel features .specifically in the claims for novelty follow-v indicator, as described in thepresent speciication and illustrated in the accompanying drawin The vinvention consists essentially of the pointed out broadly and V yshield of the motor vehicle.

flexible sid-e members are fastened, the latter f A stillfurther objectof the invention resides in the provision of an indicator einbodying the aforesaidJ functional characters istics including ahollow arrowhead to which being wound upon rollers positioned 'within a casing and adaptedl to extend with said arrowhead tofform an indicating arrow.

In connection with theforegoing, the invention is further characterized in that means are provided co-operating said -motor with said hollow arrowhead and flexible side members to extend the same when the motor is energized untilvthe arrow in its entirety has reached its outermost position and automatically recede -the saine when the electri- 'cal motor circuit has been broken.

With the'foregoing and. other objects in view which \wil1 appear more fully as the `des criptionl proceeds, the invention resides in the novel combination and arrangement or co-operating elements as hereinafter lmore specifically set forth, claimed and shown in -the accompanying drawings formlnga part of the present application, and in which Fig. 1 is an elevation illustrating a direction indicator constructed in accordance with an acceptable embodiment of my present invention, mounted upon the windshield of a. motor vehicle.

Fig. 2 is an enlarged vertical transverse section through the casing of the indicatorv vided for the. casing illustrating the association of the different parts.

Fig. 3 is a vertical section taken substantially on the'plane designated -by the line cated by the arrows.

Fig. 4 is an enlarged horizontal' section taken substantially on the plane designated by the line 4-T4 of Fig. 2, looking in the di- 3-3 of Fig. 2 looking in the direction indij' `rectioirindicated by the arrows.

Fig. 5 is a fragmentary detail illustrating the construction of the normally closed doors for the casing ofthe indicator, andy Fig. 6 is a longitudinal sectional elevation of one of the {iexible side member supportingwroll'ers.

Like numerals of reference designate corresponding compohents throughout the sev;`

eral views.

The numeral 12 tends through a casing designated in its entirety by the numeral 13, said casing being clampedon the uprights of the windshield frame 14 of theY motor vehicle 15, by means of clamping brackets 1Q secured to said casing: The casing 13 has an extension 17 on its inner or rear side, iii which the inner end of rod 12 operates. A covering 18 is pro- 13 and its extension 17 and serves to complete the latter, as shown clearly in Fig. 3. A cap 19 is carried at the inner end of the rod 12 and one endv of the extension spring 20 bears against the cap 19,

indicates a rod which ex# cANAnA, AssIGNoi.

while the other end thereof bears .upon the extension 17 of the casing 13. Th

serves to resiliently retain the rod 12 in its innermost or receded position, as clearly in-.

dicated by the dotted lines in Fig. 3.

A rack 21 is formed in the rod 12, so that the rod, 12 may be forced outwardly to extended position, as hereinafter described. A hollow arrowhead 23 is positioned on `the outer endV ofthe rod 12. A pair of flexible side members 1s spring 24 are secured at their outer ends on lthe flat sides ofthe hollow arrowhead 23, while their inner ends are mounted upon spring rollers 25 within the casing 13.

The said 'fiexible side members mayhave the words Right and Left printed thereon so that the saine will be disclosed when the' indicating arrow in itsentirety is extended. The indicating arrow described extends through lan opening 13"' provided for this purpose in the outer side of the casing 13 ed on the stub sha-ft 1 in such a manner as 49 on which the pinion 50 operates.

and its covering 18. A pair of doors 26 are provided to form a closure means for said opening 13g' and are provided with 'springs 27 to holdthe same closed when the indicating arrow is positioned within the casing 13.

l The rollers 25 are hollow and have springs 28 provided therein encircling the roller shafts 29. One end of the spring in each hollow roller 28 is f connected thereto, while the other end of' the spring is connected to the shaft 29. Each said roller shaft has a squaredend 30 and the roller shafts 29 are mounted in the casing 13 on opposite sides to prevent rotation of the said roller shafts. It is, therefore, evident that when the "flexible side members 24 are drawn outwardly during the outward movement of the rod 12, the springs 28 are wound up and serve to rewind said flexible side members 24 on the rollers 25 as the rod 12.is receded into the casing 13.

A pair of lamps 31 are carried on the transverse support. 32 and the casing 13. rIhe lamps 31 are surrounded by a reflector 33 having its open end directed towards the opening 13a, the reflector being carried on the support 32. If desired, the hollow arrow head 23 maybe made to form a like reflector adapted to oppose the reflector 33 to deflect the light against said flexible side members for illuminating purposes. Illumination of the Vflexible side members 24 occurs whenever a circuit is completed through the lamps 31, which are connected with the circuit wires 34 extending to the electric mo-` tor 35. The motor 35 is mounted in the casing so that the shaft 41 is parallel with the rollers 25. A gear 42 is positioned on thev shaft 41 of the motor 35 and meshes with and drives thegear 43 rotatably mount- 44. The gear 43 meshes with and drives the gear 45 which is loosely mounted on the roller shaft 29 of one of the rollers 25, and meshes with and drives gear 46 lsecured to shaft 47. Said shaft is rotatably carried in a support 48 extending at right-angles from the transverse bar 32.( The shaft 47has a spiral threaded portion When the motor 35 is energized, shaft 47 is driven through the gear mechanism described, and the pinion 50 is forced along the spiral thread 49 on said shaft 47 into engagement with the'. rack 21 `on the rod 12 and extends said rod outwardly together with the hollow arrow head 23 to which. the exible side members 24 are connected.y

When the circuit to the motor is broken, the spring 20 tensions the rod 12 inwardly and the springs 28 of the rollers 25 serve to rotate the shafts 29 of said rollers and ing, adapted wind the flexible side members'24 thereon.

As the rod 12'is receded, the pinion 5() is moved axially on the spiral threaded portion 49 of the shaft 47 untilthe same disengages the rod 12. f

While the preferred embodiment o the invention has been described it is ,to be understood that minor changes in the details ofconstruction, combination and arrangement of co-operating elements may be resorted to within the scope of what is claimed without departing from the spirit of the invention.
